Solving Systems of Linear Equations                               [TOC]
===================================

In this example we solve a system of linear equations $Ax = b$ were the
coefficient matrix is general, i.e. not necessarily symmetric.  We solve the
system with __lapack::sv__ which is the FLENS port of LAPACK's __dgesv__.
